The line equation is .

First find the x-intercept, let y = 0.

                             (Replace y with 0)

                    (Divide each side by negative 3)

                                   (Simplify)

Since x = 0 when y = 0 graph the ordered pair (0, 0)

To find the y-intercept, let x = 0.

                         (Replace x with 0)

                                   (Simplify)

Since y = 0 when x = 0 graph the ordered pair (0, 0)

Use these ordered pairs to graph the equation.

\
• Draw a coordinate plane.
\
• Plot the points (0, 0) and (0, 0)
\
• Draw a line through these points.
